Final Answer:
The following expression:
3 / 21-52 + 4 - 16 + [72×2-2 / 2 + (47) + 1] is A. -71
Step-by-step explanation:
The given expression involves a series of mathematical operations, including division, multiplication, addition, and subtraction.
To simplify, you must follow the order of operations, known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
Starting with the innermost parentheses, the expression inside evaluates to 94. Now, perform multiplication and division from left to right, resulting in a value of 47.
Next, handle the remaining operations (addition and subtraction) sequentially, leading to the final result of -71.
In summary, after simplifying the given expression following the proper order of operations, the correct answer is A. -71.
